Application filed April 16, 1926. Serial No. 102,516.

This invention appertains generally to new and useful improvements inplumbing and has more specific reference to a novel and simplifiedcoupling for use in connection with closets and especially with thattype known as low down closets.

At the present time, it is well known that in order to remove the bowlof low down closets, it is first necessary to remove the flush tankthereof. this being ydue to the particular construction of the couplingconnecting the flush tank and the bowl together. Thus, a great amount oftime and labor is.. unnecessarily expended in the removal and replacingof the bowl incident to the making of repairs thereto.

lt is. therefore, the primary object of the present invention to providean improved coupling for low down closets so constructed that the bowlof the closet may be removed without the necessity of first having toremove the flush tank.

Another object of the present invention is the provision of such animproved coupling consisting of a pair of independent sections which maybe readily detached one, .from the other so that the bowl of the closetmay be easily and quickly ren'ioved without dis- I turbing the flushtank.

"50 A Jfurther object of the present invention is the provision of .sucha novel coupling, the use of which will result inthe saving of both timeand labor in the positioning or removal of the 'bowl of the closet.

A still further object of the present invention is the provision of sucha coupling of the character stated which is both durable and eiicient inuse, one. which can be manufactured and placed on the market at a small40 cost and one which may be readily incorporated with bowls and flushtanks now in use.

Numerous other objects and advantages of the present invention willbecome more read- CAD 4 ily apparent during the course of the4Jrollowing description when takenin vconnection with the accompanymgdrawings.

In the drawings forming a part of this application: I

Figure 1 is a side elevation of an lmproved coupling constructed inaccordance withthe present invention and shown associated with a' lowdown closet.

Figure 2 is a longitudinal central sectional view through the improvedcoupling.

Reference mw being had more paracalarly to theaccompanying drawingswhere- 1n for the purpose of illustration has been disclosed a preferredembodiment of the presentinvention, the letter A generally indicatesth'e'bowl of a low down closet, B the flush tank thereof and C theimproved elbow coupling for connecting the flush tank and the bowltogether. It is to be understood that the bowl A and the flush tank Bmay be of any conventional or preferredv construction.

The coupling C embodies in its construction a pair of cylindricalindependent pipe sections 'and 11, the section 10 communieating with andsecured to the flush tank B while the section 11 is secured to andcommunicates with the bowl A as will be readily seen upon reference toFigure 1.

The section 10 is substantially vertically disposed and the upper endthereof is inserted upwardly through the externally threaded nipple 12formed on the bottom of the flush tank B. A lock nut 13 encircles thesection 10 and yis threadedly engaged with the threaded nipple 13, forretaining the section 10 in position. A suitable packing washer 1l isdisposed between the end of the nipple 12 and the inwardly directedannular flange `15 formed on the nut 13. The lower end portion of the.section 10 is curved forwardly as indicated at 16 and the terminalthereofis provided with ternal threads'17.

The section 11 is substantially horizontally disposed and the forwardend thereof is inserted through the externally threaded nipple 18 formedon the bowl A. Encircling t e section 11 and threadedly engaged with thenipple 18 is a nut 19, similar to the nut 13, a suitable packing washer20 being positioned adjacent the end of the nipple 18 and held in placeby the inwardly directed annular flange 21 of the nut 19. The oppositeend of the section 11 is provided with the exthe right angularlydirected annular flange or shoulder 22 and positioned between the saidshoulder 22 and the threaded end of the section 10'is a washer 23.

For the purpose of securing the adjacent ends of the pipe sections 10and 11 together, there is provided a nut generally represented by thenumeral 24. This nut is slidably positioned on the section 11 and isprovided at one end with ,an inwardly directed annular flange 25 adaptedtkrabut the shoulder 22 of the' section 11, The opposite end 2G of thenut is internally threaded to threadedly engage the threads 17 formed onthe adjacentend of the section 10.

Thus, it will be seen that when it is desired to secure the sections 1()and 11 together, it is only necessary to screw the nut 24 on theadjacent threaded end of the section 10. When it is desired to removethe bowl A, it is onlyvnecessary to unscrew the nut 24 so as todisengage the same from the section 10. The sect-ion 11 can then beslightly slipped into the bowl A whereupon the same may be readilyremoved without the necessity of having first to removethev flush tankB.

The couplings now in use are ordinarily formed from a single length ofpipe so that before the bowl pending projection which is receivedwithinthe door thus making it necessary that the bowls be raisedvertically in order that they may be removed. l

From the foregoing, it will be appreciated that there has been rovided anovel and simplified coupling or use, in connection with low downclosets so that the bowl thereof can be removed with the expenditure ofa minimum amount of time and labor. i It is also to be understood thatwhile there has been shown` and described a preferred embodiment of theresent invention, that changes in the details of construction thereofmay be resorted to without departing from or sacrificing the spirit ofthe invention so long as such changes fall within the sco of theappended claims.

' at is claimed is: v

1. The combination with the flush tank can be removed, it 1sv firstnecessary to remove the flush tank' B, inasmuch as the bowls now in usehave a de-l of said nipples and the other ends thereofr in abuttingrelation, av collar surrounding each pipe-and engaging the adjacentnipple,

ya, packing surrounding each pipe and secured against the engaged nippleby the associete collar, and means for securing the.

abutting ends of said pipes together in leakproof' engagement.

2. bowl ofthe closet, each having a passage formed therethrough andsurrounded by an outwardly projecting threaded nipple, of an improvedcoupling therebetween consisting of a pair of independent pipe sectionseach being formed of constant diameter throughout one end thereof, saidends being each slidably extended through one of said nipples, the otherends of the pipes being flanged in abutting relation, a collar member4surrounding each pipe and threadably engaging the adjacent nipple, aninwardly projecting 4annular flange formed about the Iouter edge ot eachcollar and engaging the f pipe fastened thereto, a packing elementsurrounding each pipe and arranged to be compressed between vthe outeredge of the nipple through which`the pipe passes and The combination ofthe iiush tank and);

the inturned flange of the attached collar,

and means slidable upon one of said pipes land engaging the other pipefor drawing the abutting ends of the pipes together.

In testimony whereof I aiiix my signature.
